I agree that it does sound as though you've tried everything & there isn't much else to suggest, I think if they're bored in the cage & don't have enough to do then they are much more likely to come asking for attention, time out etc but some are really quite content to just stay at home most of the time, it does make taming difficult I know, I would continue to get him out a couple of times a week as you are & do what you can during that time to get him more comfortable with you around him & a little handling but otherwise I think you may just have to accept that's how he is.
